Definitions
- the present invention relates to an apparatus and method for constructing a zone database to provide home zone services to the subscribers of a mobile communications system.
- a home zone service provides a different charging rate to a subscriber so that one of the charging rate is equivalent to an ordinary wired communication charge when the call is made within the home zone registered by the subscriber. For example, if the subscriber registers a specific area as his or her home zone with the mobile communications system, the air time charges can be charged at a significantly lower rate than normal.
- the mobile communication system collects location information (latitudes and longitudes) of the base stations, their respective communication coverage information, etc., based on the address specified by the subscriber.
- the present invention provides an improved apparatus and method for determining a charging rate for a call connection using a predetermined zone database.
- a method for constructing a zone database for providing home zone services to the subscribers of a mobile communication system comprising the steps of: dividing a service area into a plurality of home service zones; simulating communication coverage area of the base stations for each of the home service zones; detecting the pilot signal strengths of the base stations; and, selecting a given number of the base stations in the order of pilot signal strength as the home zone.
- an apparatus for providing a home zone database used to determine a charging rate for a call connection with a mobile station within a mobile telecommunications network comprising: a first storing means for storing data associated with a plurality of base stations, geographic data, system parameters, and antenna information of said mobile network; a simulating means for simulating a communication coverage for said base stations using the data stored in said first storing means; a detecting means for detecting the pilot signal strength of said base stations simulated by said simulating means; a second means for storing said detected pilot signal strength according to each of said base station; and, a sorting means for selecting a predetermined number of said base stations in the order of pilot signal strength, said selected predetermined base stations are stored in said home zone database.
- FIG. 1 is a block diagram for illustrating the structure of an apparatus for constructing a zone database for providing home zone services in a mobile communication system according to the present invention
- FIG. 2 is a diagram for illustrating the division of a service area into a plurality of home service zones, and the distribution of the base stations whose pilot signals are detected by a particular home zone;
- FIG. 3 is a flow chart for illustrating the process of constructing a zone database for providing home zone services according to the present invention
- FIG. 4 is a flow chart for illustrating the process of determining the home zone database of a subscriber according to the present invention.
- Fig. 5 is a flow chart for illustrating the process of providing home zone services based on a zone database according to the present invention.
- a parameter database (DB) 100 is provided to store various information used for simulating coverage area, such as system parameters, base stations, geographic data, antennas, etc.
- a zone data generator 200 includes a coverage simulator 220 , a pilot signal detector 230 , a pilot signal related base station data storage 240 , a sorting/selection unit 260 , a base station DB 280 , and a PN offset related data base storage 290 .
- the coverage simulator 220 makes a coverage simulation of each base station by using the information stored in the parameter DB 100 .
- the operational unit is bin. It is well known in the art that information contained in the parameter DB 100 can be represented in a bin. Through a binning process, bins of various data points are formed based on the information stored in the parameter DB 100 . Bin positions are determined from the bins. Bin positions define the order of bins along each discretized axis and can be determined from bin numbers associated with the bins.
- the pilot signal detector 230 detects the pilot signal of each base station in bin unit.
- the pilot signal related base station data storage 240 then stores the detected pilot signal level of the corresponding base station in a given bin position.
- the PN offset of the base station is also included in the base station data 240 .
- the PN offset is utilized to discern between base stations associated with users.
- the generated data stored in the pilot signal related base station data storage 240 includes the pilot signal strength, PN offset, and base station data.
- the base station DB 280 stores the base station data to distinguish between base stations.
- the sorting/selection unit 260 in turn selects a predetermined number (e.g., 8) of pilot signals in the order of pilot signal strength.
- the PN offset related base station data storage 290 performs data arrangement according to the data format demanded by the zone DB 300 , which stores the zone data files received from the PN offset related base station data storage 290 . Accordingly, each bin position, defining a home zone, is represented by the data processed according to the above process to be stored in the zone DB 300 .
- FIG. 2 illustrates how each bin position is processed using the above-described means.
- the coverage simulator (RSSI detection simulator) 220 determines the home zone 500 based on the pilot signal strength received from the surrounding base stations A to H. A predetermined number of the surrounding base stations in the order of pilot signal strength is selected according to the embodiment of the present invention.
- FIG. 3 further illustrates the process of constructing a zone database 300 to tabularize home zone services according to the present invention.
- the zone data generator 200 initially divides a service area into a plurality of home service zones in the unit of a bin, in step 3 a .
- the coverage simulation is initially made for the first home zone to detect the pilot signal strengths of the surrounding base stations in step 3 c .
- Detected pilot signals from the respective base stations are sorted according to their strength in step 3 d and a predetermined number of the base stations (i.e., 8) is selected in step 3 e in the order of pilot signal strength.
- the selected base stations defines the home zone corresponding to the one of the divided plurality of home service zones in step 3 f . More specifically, the base station data with the PN offsets of the selected base stations are retrieved from the base station DB 280 during the process of preparing the zone database. If all home zones are not detected for all divided home service zones in step 3 g , the steps 3 c to 3 f are repeated until the home zone identification variable “n” becomes equal to the total number of divided home service zones through step 3 h.
- the zone database constructed as describe above is kept in the base station or control center so that a comparison can be made to determine whether the mobile station is located within the home zone or not. Accordingly, different billing scheme can be applied to the mobile subscriber.
- FIG. 4 describes the process of determining the home zone area of a mobile subscriber.
- the control center enters the address information of the mobile subscriber who is seeking the home zone services in step 4 a . It also determines the site information of the subscriber corresponding to the address information using the GIS (Geographic Information System) tool in step 4 b .
- the zone database 300 is searched to retrieve the base station information corresponding to the determined site information.
- a given number base stations, as determined in FIG. 3, that is assigned to the corresponding site information is retrieved to construct the home zone database for the subscriber.
- the home zone database will include a given number, e.g., 8, of the base stations.
- the zone DB 300 can be used to define a home zone for a subscriber as dictated by the operator.
- FIG. 5 illustrates the process of providing the home zone services using the zone database.
- the control center determines in step 5 a whether there is a call setup request, a site registration demand, or the activation of a home zone confirmation key (e.g., *69) from a mobile station. If so, the control center detects, in step 5 b , the base station information to identify the base station serving the requesting mobile station.
- the base station information includes site ID, sector ID, etc.
- step 5 c the control center determines whether the detected base station information is included in the home zone DB that is created in FIG. 4 .
- the home zone database also includes site ID, sector ID, etc.
- control center determines in step 5 d that the subscriber is located within the registered home zone and applies a first price rate, e.g., ordinary wired telephone price rate. Otherwise, the control center determines in step 5 e that the subscriber is located outside the home zone and applies a second price rate, e.g., mobile telephone price rate.
- a first price rate e.g., ordinary wired telephone price rate.
- a second price rate e.g., mobile telephone price rate.
- the present invention provides the means for constructing a zone database for providing the home zone communication services. While the present invention has been described in connection with specific embodiments accompanied by the attached drawings, it will be readily apparent to those skilled in the art that various changes and modifications may be made thereto without departing the gist of the present invention.
